Abstract
The technical problem that is tackled in this project is the estimation of distributed inputs from only acceleration data. In this pursuit, four setups are proposed that utilize the Gillijns–De Moor Filter (GDF), aiming to overcome the limitations of the filter in this scenario and reduce the number of sensors needed. Numerical simulations are provided, although only with a beam model due to time constraints. The methods are subjected to scenarios with loads of different dynamical properties and measurement noise levels, and their performance is compared. Further testing must be performed using a wind turbine blade model to validate its applicability to the target scenario.
